Vibrating screen equipment in mineral processing has a tough job. The eccentric motion with high vibration coupled with heavy loads puts a strain on components, and especially bearings that are exposed to the elements and abrasive dust. It's an environment where equipment failure is often accepted as a cost of doing business.

— Vibratory screens are machines that, when subjected to the mechanical vibration, carry out the separation of material mixtures to granulation, or to fractions. The number of fractions depends on the number of storeys on a vibrating screen. This paper discusses the regulated electric drive of vibratory screens with one storey, used to separate the …
